XCode 7 is not supported

[konrad-g]

When running on XCode 7 I get:

lcov: ERROR: no valid records found in tracefile Coverage.info
Reading data file Coverage.info
genhtml: ERROR: no valid records found in tracefile Coverage.info
Coverage report is in lcov folder

Xcode 7 generates coverage in a different file format.

How are things with the lcov update, as of 77afcfc?

[michaelmyers]

Jon,

Pulling from master, it looks like it is almost back. I had to make the lcov scripts executable and then added get_version.sh from lcov to suppress the error created by this line.

It looks like the Line Data count is off (the numbers are gigantic, 58411*10^7, maybe an unsigned vs signed int issue) however the bigger issue I am experiencing is the cannot merge previous GCDA file: corrupt arc tag console spam followed by a crash. It generates some of the gcda files so the getcov script will process the ones available but (I believe) that crash is preventing the majority of the gcda files from being created.

The consensus after a couple of searches on how to solve the cannot merge issue is to turn off instrumentation and code coverage support, which doesn't help us out. I will report back if I figure anything else out.

Also, thanks for your hard work on the project. You are fighting the good fight.

Hi Michael - where did you get get_version.sh from?

Also, I'm getting problems. I generate env.sh from within XCode, seemingly ok, then call getcov which starts a scan for GCDA files from the root /. Weird.

[michaelmyers]

@bixbarton You can get get_version.sh from the lcov project, the development version is here on github. Xcodecoverage uses lcov to convert the coverage data to HTML.

I have not seen the root scan issue that you describe.

[bixbarton]

Thanks Michael, I put that file in place and things run smoother. The root scan issue was my mistake, not setting the environment variables correctly.

Only issue I have now is that Xcode 7 isn't generating any GCDA files for this project. Utterly bizarre. Code Coverage is on, Legacy is on.

[bixbarton]

Ok, so the reason I'm not generating GCDA files is that INSTRUMENT_PROGRAM_FLOW is set to NO. But setting it to YES causes my test run to fail. Lots of "cannot merge previous GCDA file: corrupt arc tag" entries in the console, and it then crashes in main.m showing BAD_ACCESS on the line calling UIApplicationMain.

I cannot turn INSTRUMENT_PROGRAM_FLOW on for the main target, but without it, I cannot generate GCDA files.

Anyone have any ideas for this?

[bixbarton]

Is XcodeCoverage going to be updated to work with the LLVM-COV profdata file?

[jstevenco]

FYI -- I am seeing the same behavior @bixbarton describes with the crash in main.m. Confirmed on Xcode 7.2.

[jonreid]

Thanks to everyone for investigating this while I was occupied elsewhere.

I've made the lcov scripts executable, and added the missing script. "Seems to work" so far on a library, but I haven't tried an app yet.

@bixbarton and @jstevenco, could you verify that you have the following enabled:

GCC_GENERATE_TEST_COVERAGE_FILES
CLANG_ENABLE_CODE_COVERAGE
GCC_INSTRUMENT_PROGRAM_FLOW_ARCS

[bixbarton]

I can verify that Jon. All 3 are set to yes.

I was able to generate code coverage on our project which uses the iOS 9 SDK, but the lcov version in the current tagged release (which the pod references is wrong): #43.

[jonreid]

Closing, at least for now.

Still I am getting coverage.info empty...Can some one help me please.
